FIG. 5.
Immunoblots of whole-cell antigen, rCom1, and radaA with sera derived from guinea pigs 4 weeks post-aerosol infection with 106 organisms of either the acute or the chronic prototypic isolate of C. burnetii. Sera (diluted 1:500) came from guinea pigs infected with Nine Mile (A), Ohio (B), Q217 (C), and Q229 (D). The samples shown in panels A to D are the same. Lanes 1, Nine Mile whole-cell antigen; lanes 2, purified rCom1 protein; lanes 3, purified recombinant adaA protein. Numbers at left are molecular masses in kilodaltons.
